Lord Hall, who began as a BBC trainee 40 years ago, started work at 8.30am and has been meeting staff at the corporation, which has seen its reputation battered after the Jimmy Savile sex abuse scandal.

Speaking to Channel 4 News presenter Krishnan Guru-Murthy, Lord Hall said the BBC had to learn lessons: "What I am here now to do is to say you can't ignore your history, you can't ignore what's happened, but to ensure that we work as a team in this organisation.

"The BBC is brilliant when it pulls together, that we work as a team to create a compelling vision going forward, that we create a new chapter for the BBC, I think there are a lot of big things the BBC can do going forward.

"Public service broadcasting and the BBC has a real future and actually when I left 12 years ago I thought it had a future, I think now it's got an even more important future than I did then."

"He knows the organisation. He's no fool. He'll get the right people around him. If anyone can do this, he's the top of the list. I've some confidence it will go well."

Former Labour cabinet minister James Purnell has recently been appointed the corporation's director of digital and strategy, but Lord Hall will need to hire a new director of news and director of television.

On announcing senior appointments in February, Lord Hall admitted that "there is a lot of hard work ahead" and that he hopes to "define the BBC and public service broadcasting for the next decade".
